Creating Surfaces from Point Clouds

This tutorial expects points in the format of an .XYZ file.

1. Create an empty surface in Civil 3D.

2. Expand your empty surface, then Definition.

3. Right-click Point Files and select Add…

4. Press the green cross to the top right of the Add Point File window that has popped up.

5. Open your .XYZ file.

6. Make sure ENZ (comma delimited) is set under Specify point file format and click OK to import your points file.

This uses the points file to define the surface, rather than loading each point into your Civil 3D drawing.
